1. OUVERTURE ENTRAÎNÉE PAR POINT DE DOULEUR

Êtes-vous confronté à des goulots d’étranglement persistants dans votre circuit de récupération de l’or ?? Inefficient primary crushing and grinding directly impact throughput, taux de récupération, et les coûts opérationnels. Les défis courants liés aux équipements de broyage traditionnels comprennent:

Temps d'arrêt opérationnel élevé: Frequent liner changes and unplanned maintenance on primary crushers halt your entire milling circuit, coûtant des milliers de dollars par heure en perte de production.
Réduction incohérente de la taille des aliments: Variable ore hardness leads to uneven particle size distribution from primary crushing, overloading your ball mills and reducing overall grinding efficiency.
Consommation d'énergie excessive: Inefficient size reduction processes can consume over 50% of your site's power budget, with a significant portion wasted as heat and vibration rather than productive fracturing.
Coûts élevés des pièces d’usure: The abrasive nature of goldquartz ore leads to accelerated wear on hammers, doublures, et meurt, driving up your cost per ton for consumables.
Évolutivité limitée & Flexibilité: Fixedconfiguration crushers struggle to adapt to changing ore body characteristics or increased throughput demands without major capital expenditure.

Is your operation sacrificing gold recovery due to inadequate primary size reduction? What if you could transform this bottleneck into a controlled, highefficiency process that elevates the performance of your entire processing plant?

2. APERÇU DU PRODUIT: HEAVYDUTY STAMP MILL FOR GOLD ORE PROCESSING

This heavyduty stamp mill is engineered as a robust primary crushing solution specifically for freemilling gold ores. Il est conçu pour accepter le runofmine (ROM) material and deliver a consistent, coarse sand product ideal for secondary grinding via ball mills or direct leaching feed.

Flux de travail opérationnel:
1. Consommation alimentaire: Minerai ROM (jusqu'à la taille d'alimentation spécifiée) is delivered via conveyor or feed hopper into the stamp mill's mortar box.
2. Percussions mécaniques: Une série de levées mécaniques, heavy weighted stamps (chaussures) are sequentially dropped onto the ore bed within the mortar box.
3. Réduction de taille & Libération: L'impact répété fracture la matrice de quartz, liberating coarse gold particles while reducing the ore to a target size of approximately 10 mesh to 20 engrener.
4. Décharge de boue: Crushed material is continuously discharged with wash water as a slurry through a grated screen at the mortar box end, prêt pour un traitement ultérieur.

Champ d'application & Limites:
Idéal pour: Minerais d'or en broyage libre, pilot plant operations, smalltomedium scale mining projects (150 TPH), and operations prioritizing mechanical simplicity and ease of maintenance.
Limites: Not suitable for refractory ores requiring fine grinding for liberation. Efficiency decreases with high clay content or excessively wet feed. Requires a consistent mechanical power source.
